How do the particles in an amorphous solid compare to those in a crystalline solid?
In an amorphous solid, the particle arrangement on both a macroscopic and microscopic scale has no periodicity, it is literally amorphous.
On a crystalline solid, the particles arrangement is neat and ordered. There is a periodicity to the particles.
What was the need for the invention of ether?
Ether was used in the mid-19th century as a general anesthetic in surgeries before the development of modern anesthetics. The need for ether arose from the desire to perform surgeries without the extreme pain experienced by patients, making procedures more tolerable and safer for both the patient and the surgeon.
What is value of hall coefficient of ge?
The Hall coefficient of germanium typically ranges from 0.003 to 0.006 m^3/C. It is a material property that characterizes the ability of a material to conduct current perpendicular to an applied magnetic field.
What are the uses and advantages of centigrade?
The centigrade scale is commonly used for measuring temperature because it is easy to understand and widely adopted. It is advantageous as it allows for consistent and standardized temperature readings across different applications and industries, making it convenient for comparison and communication. Additionally, many scientific formulas and calculations are based on the centigrade scale, making it a practical choice for scientific research and experimentation.
What does not change in solid matter?
Physical properties can be tested without changing the substance a new substance. Color, density, volume and melting and/or boiling point are examples of physical properties that can be observed and/or tested.
Why ionic bonding is directional?
Ionic bonding is directional because it involves the transfer of electron(s) from one atom to another, leading to the formation of positively and negatively charged ions. These charged ions are held together by strong electrostatic forces of attraction, which act in specific directions between the oppositely charged ions, giving the bond a directional nature.
Why ionic bond energetically favorable between element of group 1 2 6 and 7?
It is because of the difference in electronegativies between the elements. Groups 6 and 7 typically have large electronegativities and therefore attract electrons to them, while metals generally have a low electronegativity and therefore don't hold their outer shell electrons as strongly. The difference in electronegativities has to be above 2.0 in most cases before it can be considered as an ionic bond.
Why any electric wire get suddenly cool when electric current cutoff?
Heat in an electric wire is mainly caused by the rapid movement and collision of electrons as they flow along it, when an electric current is cut off, the flow is greatly reduced causing a huge drop in temperature.
How does CO react with ZnO thin film?
When carbon monoxide (CO) reacts with a zinc oxide (ZnO) thin film, it can undergo a redox reaction where CO acts as a reducing agent while ZnO gets reduced. This reaction can lead to the formation of zinc metal and carbon dioxide as products. The specific reaction pathway and products formed depend on factors such as temperature, pressure, and the properties of the ZnO thin film.
Is iodine molecule an amorphous solid or a crystalline solid?
Iodine molecule is a crystalline solid at room temperature. It forms a lattice structure with well-defined repeating patterns.
What are the expressions for the Fermi wave vector in 1D 2D and 3D?
The Fermi wave vector expressions in 1D, 2D, and 3D are given by:
1D: k_F = (3π^2n)^(1/3) 2D: k_F = (πn)^(1/2) 3D: k_F = (3π^2n)^(1/3)
What is the relation between angular velocities of a pair of coupled gears of different radii?
The angular velocities of a pair of coupled gears are inversely proportional to their radii. This means that the gear with a larger radius will rotate more slowly than the gear with a smaller radius. The ratio of their angular velocities is equal to the ratio of their radii.
How many tera ohm is insulation resistance of air?
The insulation resistance of air is extremely high, typically in the range of hundreds of teraohms to petaohms.
Why the viscosity of gases increases with increase in temperature?
Using the 5 characteristics of matter. the particles simply speed up, and the atrractive forces weaken. Thus, there are mroe spaces in between and there is less friction between the particles when you pour them.
What happenes when a solid turns into a liquid?
When a solid turns into a liquid, it undergoes melting. The particles in the solid gain enough energy to overcome the forces holding them in a fixed position, allowing them to move more freely. This results in the solid transitioning into a liquid state without changing its chemical composition.
What is the relation between joule per mole and joule per atom?
The relationship between joules per mole and joules per atom depends on the substance being considered. In general, to convert from joules per mole to joules per atom for a given substance, you would divide by Avogadro's number, which is approximately 6.022 x 10^23 atoms per mole. This conversion allows you to compare the energy at the atomic level versus the molecular level.
What is the difference between nanoparticles and nanostructures?
In describing nanostructures it is necessary to differentiate between the number of dimensions on the nanoscale. Nanotextured surfaces have one dimension on the nanoscale, i.e., only the thickness of the surface of an object is between 0.1 and 100 nm. Nanotubes have two dimensions on the nanoscale, i.e., the diameter of the tube is between 0.1 and 100 nm; its length could be much greater. Finally, spherical nanoparticles have three dimensions on the nanoscale, i.e., the particle is between 0.1 and 100 nm in each spatial dimension. The terms nanoparticles and ultrafine particles (UFP) often are used synonymously although UFP can reach into the micrometre range. The term 'nanostructure' is often used when referring to magnetic technology.
What can a liquid can be described as a form of matter as?
A liquid is a state of matter where the particles are close together but can move past each other. Liquids have a definite volume but not a definite shape, conforming to the shape of the container they are in. They have higher kinetic energy than solids but lower than gases.
What is an equivalent diode of a triode valve?
Hard to answer this one.
The triode is a diode with a control electrode (the grid) added.
The only useful answer is that a triode is a voltage-controlled doide.
Try asking the question so that it can be answered more usefully.
Is an amorphous solid or a crystalline solid more compressible?
Amorphous solids are generally more compressible than crystalline solids because they lack a regular atomic arrangement, allowing their structure to deform more easily under pressure. Crystalline solids have a well-defined lattice structure that makes them more resistant to compression.
We know that steam is the gaseous phase of water, so it has water in it. It also has considerable thermal energy, too, as water must be heated quite a bit (at STP) to turn it into steam. It is the thermal energy in steam which we use to drive so many different things, like turbines to generate electric power.
What is the solid state diode?
A solid-state diode is a semiconductor device that allows current to flow in one direction only. It consists of a p-n junction where the movement of charge carriers across the junction creates the diode's characteristic behavior of allowing current to flow when forward biased and blocking it when reverse biased. Solid-state diodes are widely used in electronics for rectification, signal modulation, and switching applications.
